• ODBC in SSIS 2012

  - by jamiet

  In August 2011 the SQL Server client team published a blog post entitled Microsoft is Aligning with ODBC for Native Relational Data Access in which they basically said "OLE DB is the past, ODBC is the future. Deal with it.". From that blog post:We encourage you to adopt ODBC in the development of your new and future versions of your application. You don’t need to change your existing applications using OLE DB, as they will continue to be supported on Denali throughout its lifecycle. While this gives you a large window of opportunity for changing your applications before the deprecation goes into effect, you may want to consider migrating those applications to ODBC as a part of your future roadmap.I recently undertook a project using SSIS2012 and heeded that advice by opting to use ODBC Connection Managers rather than OLE DB Connection Managers. Unfortunately my finding was that the ODBC Connection Manager is not yet ready for primetime use in SSIS 2012. The main issue I found was that you can't populate an Object variable with a recordset when using an Execute SQL Task connecting to an ODBC data source; any attempt to do so will result in an error:"Disconnected recordsets are not available from ODBC connections." I have filed a bug on Connect at ODBC Connection Manager does not have same funcitonality as OLE DB. For this reason I strongly recommend that you don't make the move to ODBC Connection Managers in SSIS just yet - best to wait for the next version of SSIS before doing that.I found another couple of issues with the ODBC Connection Manager that are worth keeping in mind:It doesn't recognise System Data Source Names (DSNs), only User DSNs (bug filed at ODBC System DSNs are not available in the ODBC Connection Manager)  UPDATE: According to a comment on that Connect item this may only be a problem on 64bit.In the OLE DB Connection Manager parameter ordinals are 0-based, in the ODBC Connection Manager they are 1-based (oh I just can't wait for the upgrade mess that ensues from this one!!!)You have been warned!@jamiet

• How to Install WebLogic 12c ZIP on Linux

  - by Bruno.Borges

  I knew that WebLogic had this small ZIP distribution, of only 184M, but what I didn't know was that it is so easy to install it on Linux machines, specially for development purposes, that I thought I had to blog about it. You may want to check this blog, where I found the missing part on this how to, but I'm blogging this again because I wanted to put it in a simpler way, straight to the point. And if you are looking for a how to for Mac, check Arun Gupta's post.  So, here's the step-by-step: 1 - Download the ZIP distribution (don't worry if your system is x86_64)Don't forget to accept the OTN Free Developer License Agreement! 2 - Choose where to install your WebLogic server and your domain, and set as your MW_HOME environment variableI will use /opt/middleware/weblogic for this how to export MW_HOME=/opt/middleware/weblogicMake sure this path exists in your system. 'mydomains' will be used to keep your WebLogic domain. mkdir -p $MW_HOME/mydomain 3 - If you don't have your JAVA_HOME environment variable still configured, do it. Point it to where your JDK is installed. export JAVA_HOME=/usr/lib/jvm/default-java 4 - Unzip the downloaded file into MW_HOME unzip wls1211_dev.zip -d $MW_HOME 5 - Go to that directory and run configure.sh cd $MW_HOME ./configure.sh 6 - Call the setEnvs.sh script . $MW_HOME/wlserver/server/bin/setWLSEnv.sh7 - Create your development domain. It will ask you for username and password. I like to use weblogic / welcome1cd $MW_HOME/mydomain $JAVA_HOME/bin/java $JAVA_OPTIONS -Xmx1024m \ -Dweblogic.management.allowPasswordEcho=true weblogic.Server8 - Start WebLogic and access its web console(sh startWebLogic.sh &); sleep 10; firefox http://localhost:7001/consoleUsually, it takes only 10 seconds to start a domain, and 5 more to deploy the Administration Console (on my laptop). :-)Enjoy!

  I recently used the "compress hard drive" option within windows. i got the horid "boot mngr is compressed" after the restart. i tried booting my system back to windows vista but it doesnt read the cd that came with my computer. i tried going into system recovery and going back to a previous date but it didnt work. i kept pressing f8 but nothing. i installed ubuntu(the ubuntu cd worked but windows didnt?) i installed ubuntu so i could atleast get in my computer, and i still wasnt able to install windows from there. my hard drive got reformatted to a ext4? and windows cant install because it doesnt read it? im not sure, but its very frustrating. my computer is a gateway gt5668e windows vista home premium with sp1. im a graphic designer and use programs such as photoshop and cinema 4d to do my projects..i have been at a unfortunate halt with my work and i am really bummed out and dont know what to do... any help?

• Dualboot Asus n56v (ubuntu / win 7 x64) - ubuntu doesn't detect partition table made by windows

  - by user76439

  I have an Asus n56v and I've got troubles installing Ubuntu 12.04 x64. I already have installed Windows 7 x64! The hard drive is: Hitachi HTS547575A9E384 My problem: The installation program doesn't recognize the already existing partitions and is offering only options where there are partitions. Can someone help me out? Is this an ACPI/IDE conflict, missing driver or conflict with Windows 7? (I'm not an expert on Linux, only working sometimes with it.) I now tried out some options concerning EFI with a GTP-table. Everything worked but I wasn't able to fix a dual boot (Windows boot loader) nor with GRUB2. The laptop is still having a BIOS, but is able to boot DVDs/CDs in EFI-mode. Now I try to avoid EFI and GTP using the old windows MBR style. I reinstalled Windows, so far no problem. When I want to try to install Ubuntu, it doesn't detect the already existing partition table. It is just showing me an empty space for the whole disk. Other threads like Ubuntu 12.04 does not see windows already install on my computer (dual installation) don't help me out. os-prober shows me a correct result. I don't know how to deal with gdisk as shown in Installer doesn't detect existing partition table/windows 7 partition. I have 750GB for the whole disk. I'm using: 90GB for Windows reserved partition + system partition, 500GB for data and the rest should be for SWAP and linux-system. How can I make Ubuntu detect the partition table?

• Deploy multiple emails to email providers, but without showing favouritism

  - by Ardman

  We are currently developing a new email deployment system. We have the system currently configured so that it reads a record from the database and loads the email content and deploys it to the target. Now we want to move this over to multiple threads. That is easily done, except we then hit the email providers returning SMTP codes referring to "Too many connections", or "Deferred connection". The solution to this is to have a thread open up a connection to the email provider and deploy n emails and then disconnect. We have currently configured the application so that it will support these session based email deployments. The problem is this, the database table has multiple email addresses in and they aren't grouped by email provider because that will show favouritism. We need to be able to retrieve a set number of, i.e. Hotmail, emails (@hotmail.com, @hotmail.co.uk, @live.co.uk) so that we are reducing the number of connections to Hotmail and reducing the risks of getting the "Too many connections" error. We are at the point now where we have gone round and round in circles trying to get a solution, so I thought I'd throw it out there and see if anyone has any ideas? EDIT I would like to stress that this application is not used for spamming purposes.

• Gaming Community CMS, with forum integration [closed]

  - by Tillman32

  Possible Duplicate: Which Content Management System (CMS) should I use? I've had a simple website that I coded myself for a while now, the site is a gaming community. It's very forum and news driven. It was a HORRIBLE idea to take on coding this thing myself. Although we've used it for about a year now, we're just getting too big, and I need to streamline our work. I need writers to post news, etc. I've been doing it through code. ( A year ago I thought it would be a cool idea ) Anyway, I've been messing with just about every CMS out there, and I'm struggling to get something that I really like. The main issue I'm facing, is a good news system, and good forum integration. I'm sort of picky when it comes to looks, its a curse. Reading on here, I see a lot of people saying Drupal is the best for the 3 things I need, community interaction, and forums. I think the main issue that I ran into with drupal, was ease of use, and themes. I am not a web designer, and I need a good theme. For an idea of what I'm looking for, go check out http://www.clgaming.net, they have forums integrated, a nice news area on home page/news section, and nice user accounts. It looks very professional, and I doubt I'll get close to that with a free theme, but their functionality is exactly what I need. Any ideas would be greatly appreciated.

• Thoughts on type aliases/synonyms?

  - by Rei Miyasaka

  I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

• Error: kernel headers not found. (But they are in place)

  - by Guandalino

  I'm trying to install the Guest Additions in VirtualBox 4.04. Host OS is Ubuntu desktop 11.04 64bit, guest OS is Ubuntu server 11.10 64bit. $ sudo ./VBoxLinuxAdditions.run After some output this line is printed: The headers for the current running kernel were not found. But the headers are installed, at least accordingly to dpkg: $ dpkg --get-selections | grep linux-headers linux-headers-3.0.0-12 install linux-headers-3.0.0-12-server install linux-headers-server install The running kernel is: $ uname -a Linux foobar 3.0.0-12-server #20-Ubuntu SMP Fri Oct 7 16:36:30 UTC 2011 x86_64 x86_64 X86_64 GNU/Linux How do I fix things so that Guest Additions installer is able to find kernel headers? Update: added full output. The headers for the current running kernel were not found. If the module compilation fails then this could be the reason. Building the main Guest Additions module ...done. Building the shared folder support module ...fail! (Look at /var/log/vboxadd-install.log to find out what went wrong) Installing the Window System drivers ...fails! (Could not find the X.Org or XFree86 Window System). I don't care for fail #2, because that's a server and I don't need X server. But I need shared folder support.

• I can't enable extra effects in Ubuntu 10.10. Please help?

  - by jasoncruz98

  I installed Ubuntu 10.10 alongside Ubuntu 11.10 to use an older version of Compiz. On Ubuntu 11.10, Compiz was enabled by default and I didn't need to use any graphics driver to enjoy the effects. All I had to do was install CompizConfig Settings Manager and enable those extra effects. That was Compiz 0.9.6. Now, after installing Ubuntu 10.10, when I first logged in, the graphics were slow. When I dragged a window from one end of the screen to the other, the whole screen would blur up and pixelate and it would be very laggy. I tried going to System Preference Appearance and selecting Extra effects on the Visual effects tab, but all I got was "Desktop effects could not be enabled". I don't know whether I should install the Additional drivers (proprietary) because my Internet is slow and it would take a long time. Furthermore, in Ubuntu 11.10, after I installed the proprietary graphics driver, I immediately went into fallback mode and wasn't even offered an option to set my desktop session to Ubuntu 3D. I didn't need the driver to run Compiz in Ubuntu 11.10, it just ran so smoothly. But in Ubuntu 10.10, everything is so laggy. Should I install the ATI/AMD Proprietary FGLRX Graphics Driver for Ubuntu 10.10 to enable extra effects? Or is there something else wrong with my system? Here is the output of lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Sandy Bridge Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Device [1002:6760] Here is the output of the same command, but in Ubuntu 11.10 (in this case the one which is correct, because I don't have the Sandy Bridge Integrated graphics controller) 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M] [1002:6760]

• .NET app - Should we use SQL Server and duplicate some reference data from an external Oracle DB? Or use Oracle and have a DB link?

  - by Daventry

  We're looking to migrate some existing Excel/Access processes into a new system which will provide the users with a Silverlight frontend to run and view the reports instead of using MS Access. The initial idea was to have SQL Server 2008 as RDBMS. The problem is that we've got some static data such as country codes, counterparties, etc which live in an existing Oracle DB. Since we do not want to duplicate that data (if possible), we were thinking of having a DB link between SQL Server and Oracle, but our firm does not allow that. So the options are either duplicate the data or use Oracle as RDBMS - surprise, the firm does allow DB links between Oracle databases. The initial idea was also to use WCF RIA Services, Entity Framework, etc which we're not sure they play well with Oracle, that's why it was decided to go with SQL Server in the first place. Would you advise to go for Oracle so that we can just link the static data? Or use SQL Server 2008 and replicate it because it's "safer" to stay within the Microsoft land? To use or not to use Entity Framework and WCF RIA Services at all? Regards. UPDATE: Thanks everyone for your answers. Nothing is set in stone yet. We'll try to import the data instead of linking, as if the other DB goes down, our system can still carry on. We're likely to use SQL Server just because most developers are more experienced with it. Even if we used RIA Services, we can swap out the Data Access Layer and use other frameworks such those mentioned below.

• Resource Acquisition is Initialization in C#

  - by codeWithoutFear

  Resource Acquisition Is Initialization (RAII) is a pattern I grew to love when working in C++.  It is perfectly suited for resource management such as matching all those pesky new's and delete's.  One of my goals was to limit the explicit deallocation statements I had to write.  Often these statements became victims of run-time control flow changes (i.e. exceptions, unhappy path) or development-time code refactoring. The beauty of RAII is realized by tying your resource creation (acquisition) to the construction (initialization) of a class instance.  Then bind the resource deallocation to the destruction of that instance.  That is well and good in a language with strong destructor semantics like C++, but languages like C# that run on garbage-collecting runtimes don't provide the same instance lifetime guarantees. Here is a class and sample that combines a few features of C# to provide an RAII-like solution: using System; namespace RAII { public class DisposableDelegate : IDisposable { private Action dispose; public DisposableDelegate(Action dispose) { if (dispose == null) { throw new ArgumentNullException("dispose"); } this.dispose = dispose; } public void Dispose() { if (this.dispose != null) { Action d = this.dispose; this.dispose = null; d(); } } } class Program { static void Main(string[] args) { Console.Out.WriteLine("Some resource allocated here."); using (new DisposableDelegate(() => Console.Out.WriteLine("Resource deallocated here."))) { Console.Out.WriteLine("Resource used here."); throw new InvalidOperationException("Test for resource leaks."); } } } } The output of this program is: Some resource allocated here. Resource used here. Unhandled Exception: System.InvalidOperationException: Test for resource leaks. at RAII.Program.Main(String[] args) in c:\Dev\RAII\RAII\Program.cs:line 40 Resource deallocated here. Code without fear! --Don

• All files gone after running fsck. How can I recover my files?

  - by cinlung

  I am a newbie in Linux. So this is my story I installed Ubuntu server 10.04lts. It worked great for many months, until today i decided to run fsck on the system partition and although it warned me, I kept pressing yes and now it will only boot into grub prompt. So i read some article and tried grub reinstall. But before performing grub reinstall, i decided to run fsck again from Ubuntu 10.04 lts for desktop live CD. The fsck painfully passes, now my drive is recognized as ext4 system and I am able to mount it again. However, all i can see is just boot directory and lost&found. I tried to perform grub reinstalling by doing grup-install stuff, now my grub is still not loading right, my files are missing, and the weird thing is that the amount I found used by boot and lost n found is only 5gb and the amount used in he hdd is 8 gb. So my files must be somewhere in the hdd. Is there any sinple way maybe a windows tool or something yo recover my files? I only need to retrieve my database backup and everything else can go. I am freaking out here. Please help.

• FILESTREAM in SQL Server 2008 R2

  - by CatherineRussell

  Much data is unstructured, such as text documents, images, and videos. This unstructured data is often stored outside the database, separate from its structured data. This separation can cause data management complexities. Or, if the data is associated with structured storage, the file streaming capabilities and performance can be limited. FILESTREAM integrates the SQL Server Database Engine with an NTFS file system by storing varbinary(max) binary large object (BLOB) data as files on the file system. Transact-SQL statements can insert, update, query, search, and back up FILESTREAM data. Win32 file system interfaces provide streaming access to the data. FILESTREAM uses the NT system cache for caching file data. This helps reduce any effect that FILESTREAM data might have on Database Engine performance. The SQL Server buffer pool is not used; therefore, this memory is available for query processing. FILESTREAM data is not encrypted even when transparent data encryption is enabled.

• digital magazine publishing engine licensing question

  - by nosarious

  I have a publishing engine I have been developing for thirty months but find myself being unable to work on it during my masters degree. I would like to make it open source in the interim to get others to use it and improve how it works. I would like to consider a licensing system that allows for multiple instances of the software for singular users (ie, a newspaper/magazine or zine hosting the code on their own). I would like to limit it from becoming the basis of a larger magazine hosting service right now because it is intended to be an integral part of a much larger publishing ecosystem which allows for the creation, dissemination and collection of publications as a free or very inexpensive service. Right now there is no license associated with it, which is why I am not posting a link here. (This system was developed to counter implied censorship for digital magazines and remove costly and confusing 'barriers to entry' for creators wishing to make interactive digital content. It is intended to be useful for free, but I would like to prevent people taking the code and using it to take advantage of others. It needs a bit of work to separate the content from the page itself to allow the access of multiple which I cannot develop right now) Any help or suggestion on how to handle licensing this code for contributions and use would be appreciated, and if anyone would like to see examples or the github I would be happy to send it.

• Should Developers Perform All Tasks or Should They Specialize?

  - by Bob Horn

  Disclaimer: The intent of this question isn't to discern what is better for the individual developer, but for the system as a whole. I've worked in environments where small teams managed certain areas. For example, there would be a small team for every one of these functions: UI Framework code Business/application logic Database I've also worked on teams where the developers were responsible for all of these areas and more (QA, analsyt, etc...). My current environment promotes agile development (specifically scrum) and everyone has their hands in every area mentioned above. While there are pros and cons to each approach, I'd be curious to know if there are more pros and cons than I list below, and also what the generally feeling is about which approach is better. Devs Do It All Pros 1. Developers may be more well-rounded 2. Developers know more of the system Cons 1. Everyone has their hands in all areas, increasing the probability of creating less-than-optimal results in that area 2. It can take longer to do something with which you are unfamiliar (jack of all trades, master of none) Devs Specialize Pros 1. Developers can create policies and procedures for their area of expertise and more easily enforce them 2. Developers have more of a chance to become deeply knowledgeable about their specific area and make it the best it can be 3. Other developers don't cross boundaries and degrade another area Cons 1. As one colleague put it: "Why would you want to pigeon-hole yourself like that?" (Meaning some developers won't get a chance to work in certain areas.) It's easy to say how wonderful agile is, and that we should do it all, but I'm somewhat of a fan of having areas of expertise. Without that expertise, I've seen code degrade, database schemas become difficult to manage, hack UI code, etc... Let's face it, some people make careers out of doing just UI work, or just database work. It's not that easy to just fill in and do as good of a job as an expert in that area.

• IDC Recommends Oracle Solaris 11

  - by user12611852

  IDC published a research report this week on Oracle Solaris 11 and described it as "Delivering unique value."  The report emphasizes the ability of Oracle Solaris to scale up and provide a mission critical platform for a wide variety of computing. Solaris built-in server and network virtualization helps to lower costs and enable consolidation while reducing administration costs and risks. Learn more about Oracle Solaris and the recently announced 11.1 update. In their conclusion, IDC reports: Today, Oracle is a multi-OS vendor that is adjusting to the opportunities presented by a significantly expanded product portfolio. The company has a long history of supporting Unix operating systems with its broad product portfolio, but the main difference is that now Oracle has direct control over the destiny of the Solaris operating system. The company has made a strong commitment to Solaris on both SPARC and x86 systems, as well as to Linux on x86 systems, and expects to continue to enhance Oracle Solaris 11 with update releases once a year as well as Solaris 12, which is already on the road map. Oracle is working to help its customers understand its strong commitment to Oracle Solaris and the product's role as a single operating system that runs on both SPARC and x86 processors. While Oracle Solaris and Oracle Linux are critical assets, the company's crown jewel is the deep collection of software that runs on top of both Oracle Solaris and Oracle Linux, software that creates a robust application environment. The continuing integration and optimization of the software and hardware stack is a differentiator for Oracle and for customers that run an Oracle Solaris stack.

• Time Zone on WebLogic Server

  - by adejuanc

  In order to configure the time zone with WebLogic Server, use the following JVM startup command: -Duser.timezone=<timezone> For example, in the java arguments in the admin console at Environments -> Servers -> Servername -> - Server Start tab, configure the startup settings that Node Manager will use to start the particular server. For example: -Duser.timezone='America/Arizona' There are many different time zones, each with its own code. For a complete list please refer to : http://en.wikipedia.org/wiki/List_of_zoneinfo_time_zones For testing, you can run the following code on WLS with a JSP, servlet, or deploying the class: import java.util.Calendar; import java.util.TimeZone; public class TestTimeZone {  public static void main(String[] args) {    Calendar calendar = Calendar.getInstance();    TimeZone timeZone = calendar.getTimeZone();    System.out.println(" your Current TimeZone is : " + timeZone.getDisplayName());    System.out.println(" Time Zone id : "+ timeZone.getID());  } }

• How to promote an open-source project?

  - by Shehi

  First of all, I apologize if this is the wrong section of network to post this question. If it is, please feel free to move it to more appropriate location... Question: I would like to hear your ideas regarding the ways of open source projects being started and run. I have an open-source content management system project and here some questions arise: How should I act? Shall I come up with a viable pre-alpha edition with working front- and back-ends first and then announce the project publicly? Or shall I announce it right away from the scratch? As a developer I know that one should use versioning system like Git or SVN, which I do, no problems there. And the merit of unit-testing is also something to remember, which, to be frank, I am not into at all... Project management - I am a beginner in that, at best. Coding techniques and experiences such as Agile development is something I want to explore... In short, any ideas for a developer who is new to open-source world, is most welcome.

• How to Manage and Use LVM (Logical Volume Management) in Ubuntu

  - by Justin Garrison

  In our previous article we told you what LVM is and what you may want to use it for, and today we are going to walk you through some of the key management tools of LVM so you will be confident when setting up or expanding your installation. As stated before, LVM is a abstraction layer between your operating system and physical hard drives. What that means is your physical hard drives and partitions are no longer tied to the hard drives and partitions they reside on. Rather, the hard drives and partitions that your operating system sees can be any number of separate hard drives pooled together or in a software RAID Latest Features How-To Geek ETC Inspire Geek Love with These Hilarious Geek Valentines How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad RGB?

• Laptop keyboard and touchpad disabled on startup

  - by JAM

  I use Ubuntu 14.04 LTS on my Toshiba Satellite L775D laptop. 14.04 is the only operating system installed. I am new to Linux and only barely scratching the surface of doing things in terminal. When I boot my laptop keyboard and touchpad are disabled (99.99% of the time) if I do nothing. The only direct effect I can have is to keep pressing the "numlock" key during boot when I notice the "numlock" light goes off. If I do this then I have a 95% chance of the keyboard and touchpad working when I am in the operating system. I am able to use my wireless mouse regardless. I have not seen any messages during boot. Previously I have tried playing with input method settings and utilities as well as language support settings. This same problem exists with the 12.... and 13... versions of ubuntu. With everything I have tried (from looking at other posts/suggestions) it seems I can have only a temporary effect. Please help me find a permanent solution to this problem. thank you.

• Can I have a computer with 2 physical HDs, & Dual boot option, one for Windows & one for Ubuntu

  - by Frank

  When my HD failed in my old computer with a dual core, I immediately went out and bought a new 6 core PC because I needed it for business and had to have an immediate solution. The old computer was otherwise a good computer. I don't want to spend a $100+ for a new operating system for the old computer because the Windows 7 Professional opperating system for the new computer will only allow one install. So, I decided to look and see if there were any free operating systems and found Ubuntu. I downloaded it and burned a live CD and would like to try it on the old computer. I found a 200 GB HD I can buy for $30 and the seller will format it any way I want. There are also other HDs available at a similar price. What I was thinking I would like to do is buy 2 HDs. Then I can have one formatted for Ubuntu 12.04 and install Windows XP Pro SP1 on the other HD for which I have the original installation CD. Then I would like to have a dual boot option so that when I power up the computer, I can choose whether to use Windows XP or Ubuntu. Is this possible? If so, how would I do it, that is, arrange it so a dual boot option presents itself on power up.
